The strategy worked brilliantly: No fans were arrested during the match, which Recife won, 1-0.

"The idea was to make the most fanatical supporters aware and help in some way to bring peace to stadiums," said Aricio Fortes, an executive at the PR firm Ogilvy, to Reuters. "At the end of the day, no one wants to fight in front of a mother, especially his own."

Sure, it worked today. But Recife might want to plan on making those security moms a fixture at matches. It would good incentive. Fans can show their passion for the game while also having the opportunity to guarantee their mothers steady employment.
